React ProgressBar Methods
beginUpdate()
Prevents the UI component from refreshing until the endUpdate() method is called.
The beginUpdate() and endUpdate() methods prevent the UI component from excessive updates when you are changing multiple UI component settings at once. After the beginUpdate() method is called, the UI component does not update its UI until the endUpdate() method is called.

defaultOptions is a static method that the UI component class supports. The following code demonstrates how to specify default properties for all instances of the ProgressBar UI component in an application executed on the desktop.
- <template>
- <div>
- <DxProgressBar id="progressBar1" />
- <DxProgressBar id="progressBar2" />
- </div>
- </template>
- <script>
- import DxProgressBar from "devextreme-vue/progress-bar";
- import ProgressBar from "devextreme/ui/progress_bar";
- ProgressBar.defaultOptions({
- device: { deviceType: "desktop" },
- options: {
- // Here go the ProgressBar properties
- }
- });
- export default {
- components: {
- DxProgressBar
- }
- }
- </script>
dispose()
Use conditional rendering instead of this method:
- <template>
- <DxProgressBar ...
- v-if="condition">
- </DxProgressBar>
- </template>
- <script>
- import DxProgressBar from 'devextreme-vue/progress-bar';
- export default {
- components: {
- DxProgressBar
- }
- }
- </script>
getInstance(element)
getInstance is a static method that the UI component class supports. The following code demonstrates how to get the ProgressBar instance found in an element with the myProgressBar
ID:
- // Modular approach
- import ProgressBar from "devextreme/ui/progress_bar";
- ...
- let element = document.getElementById("myProgressBar");
- let instance = ProgressBar.getInstance(element) as ProgressBar;
- // Non-modular approach
- let element = document.getElementById("myProgressBar");
- let instance = DevExpress.ui.dxProgressBar.getInstance(element);
